WIRIS EDITOR is a mathematical visual (WYSIWYG) editor. You can use a large collection of icons nicely organized in thematic tabs in order to create formulas or equations for any web content. You can create and edit your formulas in a visual environment, just click on the WIRIS editor icon for creation or double-click on the formula for edition. No maintenance when upgrading Moodle to a new minor version. It is based on JavaScript and compatible with HTML 5.

WIRIS EDITOR offers a chemistry toolbar. The maths and the chemistry palette are available from different icons in the rich text editor.

WIRIS CAS is an online platform for mathematical calculations designed for education. You can access a powerful calculation toolbar through an HTML page that includes integrals and limits calculation, function graphing in 2D or 3D and symbolic matrices manipulation, among others. WIRIS cas covers all mathematical topics from primary school to university level (Calculus, Algebra, Geometry, Differential Equations...).

I installed the wiris filter and math editor and it worked perfectly. However after updating to 3.0 all the equations that I created using Wiris now shows ........etc. in the question text. I have upgraded the plugins for atto and tinymce, however the icon to open wiris doesn't show up in neither of these editors, although I ensure that wiris was configured to show up in the editor.
What can I do for it to show the icon.

We're having issues where the TinyMCE WIRIS editor doesn't work properly in the second text editor on a page. For example, create a new "Page" resource and add math to both the content and description. If we then edit the page a second time, the math in the content is mangled with the addition of partial images tags. This is with the latest WIRIS and moodle 2.9.4. Downgrading our previous version of wiris editor fixes the problem.

Another problem we've noticed is that copy and paste of equations isn't working in Atto. The pasted equation is recognized only as an image by the editor. This is in Chrome and firefox under Moodle 2.9.4 with the latest WIRIS editor.

@WIRIS TEAM SUPPORT.
Yes I can confirm that I have the latest version of the filter installed. I have upgraded all the components to the latest version. This includes the plugin for ATTO and TinyMCE. I also have the wiris filter second on the list of filters with the MathJax on top. Still the icon doesn't show. I have also doubled check to ensure that I have included in the atto and tinymce toolbar configuration. For atto it is just "maths" and for tinymce it is " tiny_mce_wiris_formulaEditor, tiny_mce_wiris_CAS". Still it doesn't work.
